[1=>0]+[2=>0] yields [1=>0,2=>0] . But is there any trick to use such syntax sugar

[1=>0]+[2=>0] yields [1=>0,2=>0]. But is there any trick to use such syntax sugar for [1]+[2]. So [1]+[2] yeilds [1,2]?

note: My concern is about such syntax, not about other related PHP functions.

    This is because + is union operator. It does not append or merge. 

    [1] is array(0=>1);
[2] is array(0=>2);

    If you union it’ll become array(0=>1) as 0 key already exists in the first array.

    There is no syntactic sugar to do it. However, you can try this

    [1]+[1=>2]

    or in other ugly expression

    [1]+[count([1])=>2]

    Also syntactically [1]+[2] == [1,2] does not make sense at all. Thats python thing.
